Abstract: Laboratory bio-efficacy study of some green pesticides, Citrus leaf extract and Custard apple leaf extract both at 2% and 5% concentrations, Neem oil + water both as 2ml in 25 ml water and 4 ml in 25 ml water and green chili paste 5mg + 50 ml water and 12 mg + 50 ml water against milky white mushroom, Calocybe indica revealed that the mean mortality was highest (76.15%) in case of green chili paste i.e. 12mg + 50ml water followed by the same green pesticides with concentration of 5mg in 50 ml water, registering mortality of 68.69%. Citrus leaf extract at 2% concentration was the poorest among all recording mortality of 35.85%. The mortality achieved in Custard apple at both the concentrations is also reasonably good.
